Battery monitoring Sensor conditioners Portable power supply controls Portable instrumentation GENERAL DESCRIPTION T The ADA4096-2 and ADA4096-4 have overvoltage protection inputs and diodes that allow the voltage input to extend 32 V above and below the supply rails, making this device ideal for robust industrial applications. The ADA4096-2 and ADA4096-4 feature a unique input stage that allows the input voltage to exceed either supply safely without any phase reversal or latchup; this is called overvoltage protection, or OVP. The dual ADA4096-2 is available in 8-lead LFCSP (2 mm × 2 mm) and 8-lead MSOP packages. The ADA4096-2 is available in 16-lead LFCSP (3 mm × 3 mm) and 14-lead TSSOP packages. The ADA4096-2W is qualified for automotive applications and is available in an 8-lead MSOP package. 1 CH1 10.0V CH2 10.0V M2.00ms T 34.20% A CH1 –3.6V 09241-146 The ADA4096-2 dual and ADA4096-4 quad operational amplifiers feature micropower operation and rail-to-rail input and output ranges. The extremely low power requirements and guaranteed operation from 3 V to 30 V make these amplifiers perfectly suited to monitor battery usage and to control battery charging. Their dynamic performance, including 27 nV/√Hz voltage noise density, recommends them for battery-powered audio applications. Capacitive loads to 200 pF are handled without oscillation. Rev.

Simplified Schematic, ADA4096-2 Figure 53 shows a simplified schematic of the ADA4096-2. The input stage comprises two differential pairs (Q1 to Q4 and Q5 to Q8) operating in parallel. When the input common-mode voltage approaches VCC − 1.5 V, Q1 to Q4 shut down as I1 reaches its minimum voltage compliance. Conversely, when the input common-mode voltage approaches VEE + 1.5 V, Q5 to Q8 shut down as I2 reaches its minimum voltage compliance. This topology allows for maximum input dynamic range because the amplifier can function with its inputs at 200 mV outside the rail (at room temperature). Although phase inversion persists for only as long as the inputs are saturated, it can be detrimental to applications where the amplifier is part of a closed-loop system. The ADA409x family is free from phase inversion over the entire common-mode voltage range, as well as the overvoltage protected range that is stated in the Absolute Maximum Ratings section, Table 5. Figure 54 shows the ADA4096-2 in a unity-gain configuration with the input signal at ±40 V and the amplifier supplies at ±10 V. As with any rail-to-rail input amplifier, VOS mismatch between the two input pairs determines the CMRR of the amplifier. If the input common-mode voltage range is kept within 1.5 V of each rail, transitions between the input pairs are avoided, thus improving the CMRR by approximately 10 dB (see Table 3 and Table 4). T 1 Some single-supply amplifiers exhibit phase inversion when the input signal extends beyond the common-mode voltage range of the amplifier. When the input devices become saturated, the inverting and noninverting inputs exchange functions, causing the output to move in the opposing direction.

This feature is of particular importance in applications with power supply sequencing issues that could cause the signal source to be active before the power supplies. 4 3 2 1 0 COMPARATOR OPERATION Although op amps are quite different from comparators, occasionally an unused section of a dual or a quad op amp may be pressed into service as a comparator; however, this is not recommended for any rail-to-rail output op amps. For rail-torail output op amps, the output stage is generally a ratioed current mirror with bipolar or metal-oxide semiconductor field-effect (MOSFET) transistors. With the device operating in open loop, the second stage increases the current drive to the ratioed mirror to close the loop, but it cannot, which results in an increase in supply current. With the op amp configured as a comparator, the supply current can be significantly higher (see Figure 56). –1 500 –4 –5 LOW RDSON SERIES FET 5kΩ SERIES RESISTOR –6 –7 –48 –40 –32 –24 –16 –8 0 8 16 24 32 VIN (V) 40 48 Figure 55. Input Current Limiting Capability Figure 55 was generated with the ADA4096-2 in a buffer configuration with the supplies connected to GND (or ±15 V) and the positive input swept until it exceeds the supplies by 32 V. In general, input current is limited to 1 mA during positive overvoltage conditions and 200 μA during negative undervoltage conditions. For example, at an overvoltage of 20 V, the ADA4096-2 input current is limited to 1 mA, providing a current-limit equivalent to a series 20 kΩ resistor. Figure 55 also shows that the current limiting circuitry is active whether the amplifier is powered or not. Rev.
